Answer:
= 10.5 - 3n
Step-by-step explanation:
The explicit rule for an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
A recursive formula has the form
=
+ d ( where d is the common difference )
Given
=
- 3 ⇒ d = - 3
Thus explicit rule with a₁ = 7.5 and d = - 3
= 7.5 - 3(n - 1) = 7.5 - 3n + 3 = 10.5 - 3n
Answer:
Part 1)
Part 2)
Step-by-step explanation:
<u><em>The correct question is</em></u>
1) Suppose y varies directly as x, and y equals nine when x equals three seconds. Find y when x equals one
2) Suppose y varies directly as x, and y equals nine when x equals three seconds. Find x when y equals one
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
Part 1) we have that
For x=3, y=9
Find the value of k
substitute the value of x and y
---->
the linear equation is
so
For x=1
substitute in the linear equation and solve for y
Part 2) we have that
For x=3, y=9
Find the value of k
substitute the value of x and y
---->
the linear equation is
so
For y=1
substitute in the linear equation and solve for x
Divide by 3 both sides
